Redi-Rock Retaining Walls
We build Redi-Rock retaining walls in Ledgestone and Cobblestone block, for schools, neighborhoods, roads and backyards.
Redi-Rock blocks are large precast concrete units, made in textures like Ledgestone and Cobblestone. Here are some of the walls we've built with them.
How it gets built
How a Redi-Rock Wall Gets Built
A Redi-Rock wall holds a hill back with sheer weight: big precast blocks, stacked so they lean into the slope.
Dig Out the Base
We excavate for the wall and cut the slope back behind it, leaving room for drain rock and fill.
Leveling Pad
A pad of crushed gravel is compacted and set dead level. If the base is level, the wall will be.
First Course
The first row of blocks is set on the pad, partly below the ground, and checked for line and level.
Drain Rock and Pipe
A perforated drain pipe runs along the back of the wall in clean drain rock, so water gets out instead of pushing on the wall.
Stack the Courses
Each block locks onto the row below and steps back a little, so the wall leans into the hill. The fill behind is compacted as it goes up.
Geogrid on Taller Walls
Taller walls get layers of geogrid between courses, rolled back into the compacted fill to tie wall and soil together.
Cap and Finish Grade
Cap blocks go on top, then the ground is finished above and below the wall so water drains away from it.
